:
"Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b."

Our Take:Third graders learn the concept of whole objects (circle, squares, etc.) being broken into a certain number of equal parts, and that equal parts of a whole can be written as a fraction. First, they understand that 1/b represents one equal part out of the total number of parts. They build upon this understanding when they learn that a/b is a fraction that represents multiple equal parts out of the total number of parts. For example, if you show your students a circle broken into five equal parts, with two parts shaded, they should know that two-fifths of the circle is shaded.

These exercises can help students practise this Common Core State Standards skill.
